The German: Transportpolizei (German for "Transport Police") was the transit police of the German Democratic Republic (East Germany), whose officers were commonly nicknamed TraPos. It was part of the German: [[Volkspolizei]] and dealt with all modes of transit but primarily with trains and railroads. It consisted of approximately 8,500 men, that were organized from a national level and at district level with each Deutsche Reichsbahn district; Berlin, Cottbus, Dresden, Erfurt, Greifswald, Halle, Magdeburg and Schwerin. They wore dark-blue uniforms (that were colloquially called “blueberries”) instead of the standard green German: Volkspolizei uniform. They were organized into sixteen companies and equipped with small arms and RPG-7 shoulder-fired antitank grenade launchers. The German: Transportpolizei supervised all larger train stations and controlled the travellers, particularly at the border with West Germany, and directed traffic. Before the building of the Berlin Wall, the German: Transportpolizei controlled the S-Bahn in West Berlin (as the Deutsche Reichsbahn controlled the S-Bahn in both East and West Berlin). In the 'interzone courses' (later called 'transit courses') there was always an escort party of the German: Transportpolizei present. The service training school of the German: Transportpolizei was in Halle.
From January 1953 until February 1957 the German: Transportpolizei was part of the Ministry for State Security, in turn part of the Office of the Secretary of State. Starting from March 1957 it was transferred to the German: Volkspolizei, whose supervising inspector was Otto Auerswald.
After German reunification in 1990 the German: Transportpolizei was dissolved, with some 1200 of its personnel transferring to the (West) German German: [[Bahnpolizei]]. On April 1, 1992 the German: Bahnpolizei was taken over by the German Federal Border Guard (now called the German Federal Police).
